I tried to use svg2css inkscape extension in python, using inkscape GUI, but it resulted in no output with an error message:
Source file C:\WINDOWS\Temp\ink_ext_XXXXXX.svg9EFDKV not an SVG.
I don't know why,Plus I couldn't reach a command line to execute this extension.
I'm using the last updated version of inkscape 0.48.
This my ERROR log file generated in \Users\staff\Application Data\inkscape:

NOW, after reading extension-errors.log and downloading some required resources, that are mentioned in this file, this is my new extension-errors.log:

But I can't reach these required resources, Could any one tell me where I can reach it?
THANKS in advance

that looks like many dependencies, including shell (unix/linux) script(s), perl, and some other helper executables. the project itself is very fresh, with the sourceforge homepage not having yet been edited by project owner. So hard to come by any useful info. best bet contact the project owner Sirezero1 at sourceforge.

None of the quoted messages from the 'extension-errors.log' relate to or are relevant for the extension in question: svg2css.

Agreed, it seems best to use the resources at the sourceforge site (help forum, bug tracker) to ask for more information about correct usage and report any issues the extension has when used with Inkscape 0.48 on Windows.
